The present invention relates to a lectin-macromolecular carrier coupling complex for separating glycosylated exosomes from a clinical sample, which comprises a macromolecular carrier and lectins coupled to the outer side of the macromolecular carrier. The complex may simply, conveniently, rapidly, and accurately separate glycosylated exosomes from a clinical sample with a high separation efficiency and a good repeatability; and the separated exosomes are intact in morphology without rupturing or cracking, may be directly used for liquid detection of glycosylated exosomes, or directly used for immunology-related detection, or directly used for gene detection or analysis after extracting related nucleic acids from the exosomes.

The methods of the invention employ targeted magnetic particles, preferably targeted nanomagnetic particles, and targeted buoyant particles such as buoyant microparticles and microbubbles. Among the benefits of the invention is the ability to combine targeted magnetic particles with differentially targeted buoyant particles to achieve separation of two or more specifically cell targeted populations during the same work flow.

The present disclosure provides for a method of filtering pollutants from a contaminated fluid stream. The method includes disposing unprepared humic shale in a container, contacting the unprepared humic shale with an aqueous solution, maintaining the aqueous composition in contact with the unprepared humic shale for a period of time, drying the humic shale, and then placing polluted water in contact with the humic shale until pollutants have been removed from the fluid.

A substrate includes a double-network polymer system including a cross-linked, covalently-bonded polymer and a reversible, partially ionicly-bonded polymer, wherein the substrate has a moisture level less than or equal to 15 percent of the total weight of the substrate, wherein the substrate is porous, and wherein the substrate includes a latent retractive force. A method for manufacturing a substrate includes producing a double-network hydrogel including a cross-linked, covalently-bonded polymer and a reversible, ionicly-bonded polymer; elongating by force the double-network hydrogel in at least one direction; treating the double-network hydrogel with an organic solvent with a volatile and water-miscible organic solvent to replace a majority of water within the double-network hydrogel; evaporating the organic solvent while the double-network hydrogel is still elongated to form a substantially-dried double-network polymer system; and releasing the force to produce the substrate.
